Oh, I thought you meant that the replacement was backwards! Glad to hear it was your old one that was wrong.
The heat shield is important to minimize vapor lock and there were also supposed to be fiber insulating tubes inside the mounting bolt holes and fiber washers under the steel washers of the pump for the same reason. If these are not there you would not only be more susceptible to vapor lock but also the alignment of the pump might not be were it needs to be for proper action against the cam.
As for the vacuum lines, they are also steel with short rubber pieces of hose connecting them to the pump and to the wiper motor with a direct connection to the manifold. I believe that
Classic Tube carries reproductions of the fuel line and vacuum line and if so you can get them in either steel or stainless.
